4 Claims.

The invention relates to radiators, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially in the construction of individual radiators of the integral fin type adapted to release trapped air and to facilitate the circulation or distribution of heated air, as pointed out in the claims for novelty following a description in detail of the preferred construction.

The objects of the invention are to produce by casting or other methods an integral fin type of radiator suitable for modern distribution of radiating devices in apartments, hotels and other buildings often equipped with sheet metal type of radiators, thereby insuring efiiciency in the heating installations as well as materially reducing the cost; to construct a radiator of the fin type in cast metal that will insure a generous heating surface and yet be readily produced; to install the radiator in a manner that will materially add to the ornamentation of the apartment; and generally to provide in the aforesaid type of radiator a durable and effective heating member.

In the drawings, Figure 1 is a front elevational view of a radiator section.

Figure 2 is an end elevational view of the radiator showing the wall recess in section.

Figure 3 is a vertical sectional view on the line 8-3 in Figure 1.

Figure 4 is a front elevational view of the radiator mounting including a grille front. Figure 5 is a vertical sectional view showing the radiator recess and the radiator mounted on the frame of the grille and the radiator itself in elevation.

Figure 6 is a vertical sectional view of the radiator shown in relationship to the frame and grille.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings, the upper circulation chamber is connected to the lower feed and return chamber 16 by the vertical tubular passages 17 from each of which the fins 18 project frontwardly and rearward: these fins extending in upward inclinations from the rear to the front in three distinct planes, the rear sections 19 being of a gradient greater than the cen- QO tral sections 29 and the front sections 21 being in a substantially parallel plane to the rear sections 19.

The fins of the one vertical tube are quite distinct from the fins of the other vertical tube though quite adjacent to one another and the fins as a whole in each lot taper downwardly, that is to say, the fins shorten as they approach the bottom and are spaced to form the passages 22 for the hot air to flow into the room or apartment.

The pipe 23 connects the radiator to a circulatory heating system and extends into the recess 24.

Sections may be added on by connecting them through the plugged holes 25 as customary in joining up sections.

The recess 24 is the usual shape of a radiator recess frequently found in apartment houses, and these radiators may simply be mounted in said recesses and supported from the bottom but for greater embellishment to the apartment it is much more satisfactory to have a grille front, indicated by the numeral 26.

This grille front in the present invention is shown as a frame, that is to say, a metal frame in which any pattern of grille is introduced, but the pattern here shown is particularly suitable to the fin type of radiator already described for enclosure in this frame 27, the grille work comprises fancy patterns 28 secured to and be- 0 tween parallel bars 29.

These parallel. bars are so spaced as to meet the fins 18, while the tubular circulation passages above and below the riser and return pipes are welded to the frame 27.

Consequently the grille front and the radiator itself becomes a unit, and this grille frame is introduced in the margin recesses 30 surrounding the main radiator recess.

The frame wall will be flush with the wall 31 of the apartment and will present a very handsome appearance being usually made of polished copper or brass or other metal that will lend itself to a good finish.

The introduction of the heating fluid from a circulatory system into the radiator heats up the surfaces of the radiator including the fins and the consequence of this is that any air trapped behind the radiator flows outwardly and the passages between the fins facilitate this through the grille front into the room to be heated leaving no trapped air.

The circulation is maintained by the upwardly inclined passages, the walls of which are in any event hot in order to distribute the heat emanating from the heating fluid coursing in the radiator. Also the grille will become hot, for the heated air to some extent obstructed by the defiecting nature of the fins, finds a little more resistance in passing through the grille which is practically a heat register.

What I claim is:

1. In a radiator, a cast metal section having a plurality of riser and return tubular passages, each tube having an individual column of fins tapering from the top downwardly and forming tortuous passages and deflecting plates for the trapped air from a wall recess and also heating surfaces in the distribution of air in a house or an apartment.

2. In a device of the kind described, a wall having a radiator recess, a grille front contained in a frame recess in said wall surrounding the radiator recess and a radiator having its circulation chambers welded or otherwise attached to said frame and connecting pipes to said chambers surrounded by upwardly directed fins forming passages leading to openings through the grille work.

3. In a device of the kind described, a wall having a radiator recess, a grille contained in a frame mounted in said wall surrounding said radiator recess, said grille having partially horizontal bars and ornamental metal work therebetween and secured thereto and a radiator in said recess having upwardly extending fins from said walls registering with said bars.

4. In radiators, a casting forming a wall for an enclosed cross stream of water widening out at the ends to form wall sections for feed and return streams of water flowing at right angles through a plurality of the castings, each cross stream wall having individual fins spaced and incline'd and adapted to form passages from a wall recess for the circulating air and for any air likely to be diverted from the circulating streams.
